This connection, as is of course understood, permits the needle-bar 14 t0 be the needles is changed so as to vary the 50 vthrust of 'the needles and thus maintain vertlcall lthe'. same coogierativ'e position of needes and Iooper in l'the lateral world' positions ofthe needles. To the lower erriil of the needle'fbar 14.is attached a needleand screwp22 servca'tnart I3 which is,

.This needle holder I!) has an extending portion 23 in which is secured, hy a screw 24, a needle 25, and projection 2li, through whieh a hole T is liored, serves as a tneans l'or leading the thread lo needle 25. 'lhe axis ol' the needle-liar I-'l is eoineidenl with Ille axis of the lnoper S, and the distant-e Ahetu'een the eenter ol' the needle-lull' Il and the needle' '.'i is substantially the distance between the axis ol' the said hook and the periphery of thesatne, plus the thickness ofthe needle, so that the needle operates just. outside oI' the ns enahling a heak 28 I'ornied on ,looper, th

'l'he needle-har I-'l is tuhularalal has Ioeated in its upper end a bushing .29 and in its lower end a li'ushing III) which serve as a hearing for a second or auxiliary needle-har 3| which extends through the sanne and which is also tubular. 'lo the. lower end ol' the needle-har 3l l attach a see-ond or auxiliary needle holder 32, which' is seeured Io the said har hy nieans ol' the screw lf3. New dle-hohlerl. has formed on it projections :I4 alnl 35 which are adapted to enlhraee the part 36, of extension -23 ol' holder In, see Figs. It) and I2. 'lhis formation ol' the 95 smalle-holder 32 pmvents any vertical movements of the same and through it an vertical movement of the. auxiliary needle-har 3l, lult at the same time it permits the needle-holders 32 and I!) to he meillated lator- 100 ally imle|x-ndently of each other. 'Ihe needle-hohler 32 carries a needle 37, held hy means ol' screw 24X, and has formed in it a. thread eye or, guide 38 which is so located and formed as to roperly lead the thread to 105 the xeedle. "'lo-t le u per elul ol' the ncedle` har I4, l attach a col ar 39 h means of set screws 40, the collar having a iole 4I formed in it which serves as a mcepttwle lor an extended end of a. coiled spring 42. To the upper end of the auxiliary' .needle-har 3].is ehuapeil a collar 43 whichhas an extending arm 44, the said arm heilig engaged by an end 45 lof the spring 42. l In suitable hearings in the arm of the ma- 115 chine. is mounteda presser-bar 46, the lower end ol' which isv provided 4with 'a saw-cnt in' which is located a presser-foot 47 adapted to swing on the .pivotal screw 48, a slot 49 being formed in the shank so as to permit the presser-foot to have a slight vertical movement relativelyr toits bar.l In the u p r end lof the shank oil the said presser-foot 1s ormed a notch 50 which is adapted to embrace the lesser-bar and thereby prevent the presserA 125 oot from swinging laterally on its pivot. A `coiled spring 51 isconnected at one end to a screw 52 set-,in 'the .teaser-bar and at the other end to' awww set in the presser-foot v saidprin'g' being thus adapted to draw the 130 t Y collar 85j the latter' being while the n t has an extended hub'58 which [erlyzlocating the said cam' on the f Affor holding it rigidly'andpreventin it i :anmtovement with igespect to the ub.

'operatively engages .6,0 means ofs'. `iws 116, acts to-fkeep t presser-afoot upwardly so that th'e notch 50 engages the teaser-bar and prevents lat,- .eral movement? of the :esser-foot' and thereby securely locks t presser-foot in 6 operative position. When it is desired to move the presser-foot to one side or to the 'tion shown in Fig. 2, the presser-bar is ligted and the presser-foot'. ressed down- ,wardly to thenotc from the presserfbar, after which 1t is swung laterally on its pivotal screw 48 and retained thus by spring 51. ATo the upper end of the resserbar is attached a collar 54 in which is eld an upwardly extending rod adapted for en` gagement with the extending arm 44, and `'thereby serve as a stop for the said arm. 54 is circularly adjustable on the presser-bar 46 by any suitable means. This construction serves as a means for regulat- 10 ing the extent of the lateral mpvement of the auxiliary needle 37.

By -adi'usting theA collar 41 circularly on gthe' need e-bar 14 b screw 41X, it can be Y 'plearly seen that the tension of the sprin 42 25 exerted on the arm 44 can be increase or decreased'and that byadjusting the collar 54 cireularly on the resser-bar 46, the locagtion or'the extent o `the lateral movement -fneedle 37 can be'eoutrelled.

fif'l'o'l will now describe-the .means I provide l l for moving laterally the lneedle holders in this "machine, -f" "L -To the upper shaft C'is attached a bevelgear 56 whi meshes with the bevel-gear 57,' in' size twice the diameter of the former,

gear 57 tur'ns'once.l The gear 57 is adapted to rotate in a-bearin 59.which is attached' to 40 thearm ofthe mac ine by screws 60 and 6l, 'f l a thin plate 62 attachedto the end of the hub 5'8"!:etai'ii`s the gear 57 inv operative' ositon as )shown m Fig. v14=` -To the hub 58 attach a ,'cam 63'by means of a screw 64. A pin 65 the hub.58, and extending from formed on "i -the center thereof sei'ves'as-a'means for progsaid hu from he arm A of the machine, is attached a v bracket or beari'n 66,- b means of screws "665, land in whie are ocatedy two short 67j andt 68.1; 'Ilo the rear elnd rlif the (sliaid are .a tac eg ective y (epen ing l.giglio-71 has a way 72 walls 73 and E4 of saldway. Ears 75-and 76 are formed on the yoke 7l which are pivotally attached, by 77 vand 78, to the amis60 --parld respectively. This construction, as i will'be elearlyfseen by] reference to l5 e walls of the way 72 ,in llel vertical Aplanes throughout its latalzi'- movements and impart to the arms 69 so that thegear 56 turns twice' and 70 movements of equal extent and keeps said arms in parallelism.

The three-comered or trian lar cam 63 is so constructed that during su tantially the first quarter of its movement it moves the arms 69 and 70` laterally in one direction and then during substantially the second quarter of its movement said arms are at rest, then during substantially the third quart-er of-its movement the said arms are moved hack to their initial position after which during the fourth quarter of its movement the said arms are ain at rest. The` cam is of course so timer that it moves the arms 69 and 70 laterally when the needles are diseng .d from the work.

n a zigzag sewing machine it is, cf course,

it becomes desirable to use. a two-to-one movement between the needle-bar drivingshaft and the cam w ich moves the needles laterall It. is also, to be miderstmxl that when .this two-to-one movement is used, thc cam movement is divided into four arts; the first part which moves the needles aterally while disengaged from the work; the aecond part which 'ves no lateral movement to the needles .so t at reeiprocation in a fixed vertical plane may be given the needles; the third part which again moves the needles laterallyto the first or anothei'posit-ion; and the fourth part which again holds the needles from lateralmovemen't during the vncxtreciprocation. .The several parts of the` cam are of'equalextcnt, as herein shown, so that from the time .the cam commences .to make its movement tothe time it finishes' the said movement, the driving-shaft turn's snhsta'ntially half around and the movement is imiform in bothA directions. By the use of my improved devices herein dischiaed,`l got the desired movemen from i cam, and thisis true whether I use short depending arms or long depending arms, for thc reason that thejaws 73and 74 always remain v'ertical'no-inatter what the extent of the lateral movement of the arms ma he.

thc three cornered The intermediate means, by which thc needle-bars areioscillated or turned laterallv from the movement of the cam 63, are as follows: To thc' forward cnd ofthe short shaft 68,` I attach a downwardly extending segment-arm or lever 79, in which is l'ormcd a segment-al slot 80,' in which is adjnstuhly hold on'e end ol' a pitman 8l, the other ond of which is suitably. lormcd to, embrace a hall 82, formed on tie end ol" a pin .'3. fixed as presently described.

is adjusted to the right or'leftas may he desired. The pinv or stem 83 is mounted i .i a downwardly extending tubular arm 85 which arm, at its up er end,'is jouruuled on n liushing'Sli, tliesaid bushing heilig secured in the arm of the uiaehiiiehy a pin or screw 86", a eolliir87 serving as anieans for retaining the arm or lever 85 in its working position on the h v bushing 86, and the collar being held to ythe bushing by-sere'w S7". l n an enlargement of tlie'liore 88, formed in thc arin 85, is located a tube 89 which depends from the arm 85 andl passes through the. outer end 90 of iin arm 9i attached to the needle-har I4, hy screw I4", as is elearly show u in Fig. 5. The tuhe 89 is of sullieient extent to reiuain in engagement with the end 90 of the arm 91 in any of the vertical osit-ions 4ol the needle-liar and is held in tie arm 85 by thestem83 passing through both the tube 89 and the arm 85. in the'above arrangement of parts, it. will be clear that as the cam 63 is rotated,the

arm 79 is oscillated, and through it and the- 'interinediatc connections, the needle-bar 14 and needles and 35 are oscillated the latter about the periphery of the looper 8. As the end of the connection 81 is adjusted towards or from the pivot of the arm 79, the extent of the lateral movement of the needles is increased or decreased,the pivot of the arm 79 being indicated b the end of the connection 81 is located over thel said pivot 92, no' lateral movement will be imparted to the needles. -As theiiuxil-` -`8.15 iary 'needle-bar 3l'is mounted in the ne'edlehar 14 and connected thereto to move-axiall therewithl by means of s ring '4 2 it can be clearly seen that the ssi needle-bar 3l will turn with the needlebar 14 the tension of i uw wasps being mh dat ii holds uw 'needIeclam ngog'etherasshownin Fig. 8. As l the needle-c 32 and 19 are interlocked, as shown in the'several it'is ofcourse clear that themovenient of the needles'vertically 1s positive, and as the two needle-bars are securel connected. by means. of the I spring 42,.t t the movement of the needlebars to the left is synchronous until the arm :44 comes into engagement with the rod 55.

As this 'e'ngagement takes place', the needlesv are positively separated against the action of the spring 42, the n eedle 25 being moved away from the suxihary needle 37 and the extent of theseparation of the said needles.- to

depending upon the 'a'djustmentof the rod and the time of contact of arm- 44therewith.' Fig. 11 shows the needles separated,

and taking the position of the needleclam` as shown in this figure, it will be seen that t e clamp 19 is the one that is rigidly attached to the needle-har 14 so that 'the return orri hthand movement of thel said clamp wiliibe' positive and that the auxiliary not move to the right u ntil said clump 1.9 ence gages it thus also the return'moveh' y reference character 92. When -Tl clamp 32 will F1 .it' again into ie hmeut of the clamp 32 tive. The auxiliary needle-har 3l, and the needle-bar 14 are connected b means of the s ring 42 as fore stated, ut said auxiliarly needle-bar ia not operated in either direction by said tion that the needle-bai 14 moves spriig. The tension of the spring draws in t e v i w en it is moving from right to left, hut when this'movement commences the needle holders iieedle-bar comes into contact with the stop pin 55, the lateral movement of the auxili needle-bar is arrested, aml it has no further movement until the return movement of the needle-bar 14 has been made to a sufficient extent to bring the needle holder carried by ement with the auxiliary needle holder, w along by the movement of the needle-har 1.4. It is thus seen that the spring 42 is actuated iiainst its tension by the needlear 14 when t ie movement of the auxiliary har is arrested by the stoppin 55, and that it is again re turned toits normal istion when the needle holder carried by t ie needle-bar 14 comes into contact with the auxiliary needle holder. uis it is seen that during the time that the spring 42 is actuated the auxiliary needle holder is not moved lateral] f, so it cannot be said that the auxiliary need e-h laterali in either direction by the spring 42.

y -It is t erefor'e to be understood that the -usual conditions ofpusliing a part 'tively laterali in one direction of a spring, and then depen of said spring to return said position is not present in' this machine. The auxiliarybar is operated laterall directions by the movement of t bar 14, and the movc'mei'its of this bar are positive, so the usual. limitations as to speed when a I part is actuated by a spring, are not present in 1tliaifii constrncltion. 8 i 2 h 4effi, to ".2 an( 9,s owi other foriiig'of this needle-clamps, t ng the clamp 32 is passed a screw 93-which engages the needle-clamp y19 and can lie justed-so as to keep the said 'clamps si'iit'ably apart or so .the needles will not'get so close getherss they are, for example, in Fig. 8. In practice however,' should a greater dis tance bel should it be desired to bring them closer to ar is actuated esired between "the needles, .or-

en the latter is again carried nst t e action ngon the action toitsinitial' ies in both lll gather, the clamps would be constructedpac l cordingly, but ofcourse where various lateral.

positions might be desired, the screw 9'3, or something similar, may he used to advantage. The presser-footI as best shown in 'g. 27, is provided with -a curved transverse needle-slot 94 two slots for gui ribbon, one in t e foot in front of the iso iss
